Be seen today
Seek prompt medical advice if symptoms are worsening, you are losing weight without trying, you cough up blood, or fever continues.
Earlier assessment is particularly important if you have HIV, have received a transplant, or take immune-suppressing medicine.
These symptoms can have several causes, but they need urgent assessment.

Does any of this apply?
Book an appointment
Arrange a routine medical appointment if you develop ongoing fever, cough, chest discomfort, unusual tiredness, or shortness of breath after disturbing soil or material containing bird or bat droppings.
Mention where you have lived or travelled, even if the exposure happened outside your current area.
Every sign above is quoted from the sofidex article on Histoplasmosis. If you are not sure, err upward — it is always reasonable to be checked.
